Leona bought a 1-year, $10000 certificate of deposit that paid interest at an annual rate of 8 percent compounded semiannually. What was the total amount of interest paid on this certificate at maturity?
(A)$10464
(B)$864
(C)$816
(D)$800
(E)$480

答案是(C)...有點不太了解題目意思...還請各位幫忙看一下..謝謝

大致上的意思如下：
Leona買了一張一年期的債卷，價值一萬元，可獲得年利率8%，每半年計算一次，複利計息，請問在一年後(到期)的時候總共可以得到多少利息?
Ans: 半年計息一次所以每次是4%，一年為期，所以計算利息的次數是兩次，一萬的4%是四百，10400的4%是416，所以利息一共是816元。
請參考指正，謝謝！
